在生物方面,多硫配位環境在許多金屬蛋白質,例如固氮酵素,氫化酵素,CO脫氫酵素以及金屬硫蛋白的活化中心中皆扮演著關鍵的角色。因此,化學家藉由合成多硫配位環境的生物模擬金屬錯合物以瞭解金屬與多硫配位之間的基礎化學。我們實驗室也根據這跟研究背景發展硫金屬化合物。在這個研究中,我們著重於設計及發展一系列新的四芽硫磷配位基,並合成一系列其金屬錯合物。
在此研究的第一部分中,我們根據取代基的不同,設計以及合成四芽硫磷配位基H2[P2S2’] 以及H2[P2S2”] 並且經由X光單晶繞射儀、1H and 31P NMR核磁共振光譜儀以及電噴灑游離質譜來分析與鑑定。
在第二部分,我們合成了三種以P2S2衍生物為配位基的金屬錯化合物,Pb(P2S2”) (1)、[Pb(P2S2”)]2[Pb2(P2S2”)2] (2)以及[Cd(P2S2”)]2 (3),並且透過X光單晶繞射儀及光譜分析對其鑑定。錯化合物1為單鉛錯化合物包含一個P2S2”配位基組成。化合物2由單鉛錯化合物以及其二聚體共結晶組成,且單鉛錯合物及其二聚體在不同溶劑條件下不會相互轉換。錯化合物3是雙鎘錯合物包含兩個P2S2”配位基所組成。
Metal centers with sulfur-rich coordination sphere are present in many metalloproteins, such as nitrogenase, hydrogenase, CO dehydrogenase and Metallothioneins. In order to understand the fundamental chemistry of metal sulfur interaction, many efforts have been devoted into develop biomimetic metal complexes that have sulfur ligation environment. Based on this motivation, we have been studying the chemistry of metal thiolate complexes in our laboratory. At this particular work, we developed new type of tetradentate dithiolato-diphosphine ligands as well as their corresponding metal complexes.
In the first half of this thesis, the syntheses of these dithiolato-diphosphine ligands with different substitutions, H2[P2S2’] and H2[P2S2”], are described. A series of physical methods such as X-ray crystallography, 1H and 31P NMR spectroscopies and ESI-mass analysis have been applied to characterize the obtained products.
In the second half of this thesis, three metal complexes of P2S2 derivatives Pb(P2S2”) (1), [Pb(P2S2”)]2[Pb2(P2S2”)2] (2) and [Cd(P2S2”)]2 (3) have been synthesized and characterize by X-ray crystallography and spectroscopies. Complex 1 is a monolead(II) species binding with a P2S2” ligand. Compound 2 contains a monolead(II) unit and its dimeric unit that co-crystallize to form the crystalline solid. The monomeric and dimeric forms are not exchangeable in the solution state according to the solvent- variable spectroscopic studies. Complex 3 is a dicadmium(II) species binding with two P2S2” ligands.
